J. BQOAMPBELL, OF CINCINNATI, OHIO.

Letters Patent No. 100,256, dated March 1, 1870.

IMPROVED SPRING-BED BOTTOM.

The Schedule referred to in these Letters Patent and making parti of the same.

To all whom. it ymay concern:

Be it known that I, J. B. CAMPBELL, of Cincinnati, in t-he county of Hamilton, and State of Ollio, have invented a new and useful Improvement in Bed-Bottoms; and 1 do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making a part ot' this specitication.

First, I use a steel-wire spring, A, made iu the shape of a spiral cone, ruiming to a small circumference at the top, and the end t of the wire at the top of the spring is turned up vertically about one-quarter of au inch or more, andthe end of the wire at the bottoni or large end of the spring is turned down vertit-ally about onehalf of an inch, or more, making a spring shaped as shown at Figure 3 in the drawings:

Second, these springs are connected to cross-bars B of a lengt-h to suit the -width of the bedstead, by inserting the half-inch extension of the' wire at the hottoni ot' each spring into a suitable hole in the crossbar. As many springs may he put on the crossdiar as there are intended to be used of slats, and then these springs are to be fastened on by extending a band, C, of webbing, or equivalent flexible material, and auot-her band, I), ot'metal or other suitable sti material, secured at the ends to the ends of the cross-bar, and extending over the tops of all the springs.A thereon.

The quarter inch extensions of the wires at the top ofthe springs are to be inserted into suitable holes iu the bands, thus holding the springs to the cross-bar and making a spring cross-bar complete, as shown at Figure 2 ot' the drawings. As many of these spring cross-bars may be used as desired in eacl1.bed-bottom.

rIhird, suitable slats E are used, ruiming lengthwise of the bed, suitable holes being made in them where they cross the spring cross-bars, and into these 'holes are inserted the quarter-inch extensions of the wires at the tops ofthe springs. Thus the sla-ts are held in their places with or without other fastening.:

Tlxe wholebed-bottom is light,.durab1e, and portable, can he easily taken apart, and is complete in itself'.

W'hat I claim as my invention, and desire t'o secure by Letters Patent, iso The construction and arrangement of' the exible bands C C and sii-iii` bands D D, in combination with the springs A A, having vertical projections a a and l b, and with the cross-bars B B and slats E E, as and for the purpose herein specified.

J. B. CAMPBELL.
